[Q] Official update doesn't work - LG Optimus 4X HD

Hi all,
I just got my new 4x HD. I have 4.0.3 (V10f non-European) on it, and want to use PC Suite to upgrade to 4.1.2 (V20c). After connecting my phone to PC, I start the PC Suite and start update. It confirms the version, and download the firmware. When it starts to update at 4% it reboots to S/W Upgrade mode. After it goes up to 5% and shows an error, and the update process stops. Tried it several times same error at the same time. I have tried with LG Mobile Support Tool, and it stops at 5% again. I have windows 8 x64 with all drivers and both softwares up-to-date. Does anyone has solution? Does anyone have the same problem?

Before update make sure you select LG Software
Then try to reinstall all drivers.
If it also not work use KDZ to flash v20x. In General Section there is a Tutorial

Phone Stuck in Download Mode - Computer Don't Recognize Phone

Hello,
I was recently trying to load a stock rom on my LG540 and the process was interrupted because of a power failure. But the phone luckily booted into "download mode". I want to reflash using the procedures discussed in various posts on bricked phones, but my computer can no longer recognize the phone. The KDZ updater reports "Phone not Found". The correct drivers are installed and I am running windows 7 home edition.
Any thoughts as to how to get the computer recognize the phone?
Thanks, MN
maybe using "Run as administrator"
Try installing these drivers, they helped me when I first used KDZ. The links are from a hungarian site.

I think the bootloader is corrupted, it's basically "bricked", but not fully
Drivers must be the issue. Try uninstalling LG driver, reinstall it or use Windows Update to install drivers.
Bricked GT540
Maybe you can use LGDP2 ??

problem in updating

hi
i was updating my phone with standard method with lg program.. (without downloading kdz file separately)
but an error occurred in 15% , " ..
"problem communication between cell and phone"
and my phone has locked in s/w upgrade mod and don't turn on.. even if i put the battery off and insert it again it turn on , in s/w upgrade mod...
please help..
If it's still at 15 % it shouldnt even have started flashing U are lucky so to say
Just pull out USB and battery, wait a few seconds and restart. Then try to install the latest drivers, maybe run it as admin or another PC if available.
If it's stuck in bootloop, try emergency recovery in B2C tool (LG update tool), or read in my noob how to, how to unbrick devices.
Also this thread needs to be in Q&A
I was using 64bit PC and had the same problem then I used another PC and the problem was gone
Had the same problem. Resolved using emergency recovery in LG tool, but using another pc.

Before flashing kdz try wiping data/factory reset and format system. After that turn off the device from recovery and flash kdz. Ofcourse dont forget to backup ur stuff.

Your only chance is (in my view) to restore backup, if you have any, from an external device only then you can get your IMEI back. Otherwise look for a thread with same problem where someone posted some options.
Good luck.
Same thread. A little search would've helped: http://forum.xda-developers.com/showthread.php?t=2786001
